Sort desktop icons

Hi,

I'm wondering how I would be able to sort desktop icons, say by name.

This is the handle of the desktop control:

$ListView = ControlGetHandle("Program Manager", "", "SysListView321")

But then how do I sort the icons? I've looked into the RegisterSortCallBack, SortItems and SimpleSort, and I've tried to use them according to the examples, but without any luck (i.e. nothing happens).

I hope somebody can help me out.. Thanks in advance!
